In the center of the gasket within your hose connector there is a device called a “Depressor.” You can use the slotted top of your Tstat screwdriver to raise, lower, or remove this depressor from the hose connector.

As you move throughout your day, moving from unit to unit, take notice that some valves allow the “valve core” or stem in the CoreMax to sit LOWER than normal (resulting in them not being depressed when you gage up to the unit) or HIGHER than normal (This can push the depressor further into your hose connector)

It is a good idea to regularly check on the depressor height in your gauge connector to ensure that the pressures brought to your gauges are right. Looking at them also ensures that you’re looking at the gaskets so you know when they need to be replaced.

Now get out there and keep your depressor height right!
